The reason why Su Mo did not use his full power was because the powerful energy fluctuations would be easily detected by powerful enemies in the distance, and he wanted to leave some origin power/energy to deal with the enemies that came after. He had killed too many people, and he could not absorb all of them in one go.
Just like this time, even if he had only killed 60,000 to 70,000, Su Mo doubted that he had absorbed even one-tenth of it.
When he thought about how he had wasted so many lifespan, his heart bled.
"Hurry up and level up. Hurry up and hold the second advancement ritual.
When the second advancement ceremony was successfully completed, the game interface would not only open new functions.
The range and speed of absorbing vitality would also be further expanded.
At that time, he would definitely not waste so much as he did now."
Su Mo took a deep breath and slowly calmed down.
Then, he turned his gaze to the game panel.
